A. Child's ticket = $5.60, adult's ticket = $11.20 B. Child's ticket = $2, adult's ticket = $4 C. Child's ticket = $4, adult's ticket = $8 D. Child's ticket = $7, adult's ticket = $14 \

Answer 1

is c the reason is 4x3=12 8x2=16 12+16=28

Answer 2

2a + 3c = 28
a = 2c

2(2c) + 3c = 28
4c + 3c = 28
7c = 28
c = 28/7
c = 4 <== childs ticket

a = 2c
a = 2(4)
a = 8 <== adults ticket
